The IoT link communication protocol provides service to the Network Layer. There are various protocols and standard technologies specified by the various organization for link protocols.

Bluetooth

Bluetooth may be a short-range wireless communication network over a frequency. Bluetooth is usually integrated into smartphones and mobile devices. The Bluetooth communication network works within 2.4 ISM band frequencies with rate up to 3Mbps.
There are three categories of Bluetooth technology:
1. Bluetooth Classic
2. Bluetooth Low Energy
3. Bluetooth SmartReady
The features of Bluetooth 5.0 version is introduced as Bluetooth 5 which are developed entirely for the web of Things.
Properties of Bluetooth network
• Standard: Bluetooth 4.2
• Frequency: 2.4GHz
• Range: 50-150m
• Data transfer rates: 3Mbps
Advantages of Bluetooth network
• It is wireless.
• It is reasonable .
• It is straightforward to put in .
• It is liberal to use if the device is installed with it.
Disadvantages of Bluetooth network
• It may be a short-range communication network.
• It connects only two devices at a time.

Bluetooth Low Energy

Bluetooth low energy (BLE) may be a short-range communication network protocol with PHY (physical layer) and MAC (Medium Access Control) layer. it’s designed for low-power devices which uses less data. BLE always remain in sleep mode except when the connection between devices is initiated and data transmission occurs, thanks to this it conserves power of the device. Bluetooth low energy follows the master/slave architecture and offers two sorts of frames that are adverting and data frames. Slave node sent the advertising frame to get one or more dedicated advertisement channels. Master nodes sense this advertisement channels to seek out slaves and connect them.

Z-Wave

Z-Wave may be a wireless communication protocol with the frequency of 900MHz. The ranges of Z-Wave lies between 30 meters to 100 meters with the info transfer rate of 100kbps in order that it’s suitable for little messages in IoT applications for home automation. This communication protocol operates on mesh specification with one and a number of other secondary controllers.

Properties of Z-Wave protocol
• Standard: Z-Wave Alliance ZAD12837 / ITU-T G.9959
• Frequency: 908.42GHz
• Range: 30-100m
• Data transfer rate: 100kbps
Advantages of Z-Wave protocol
• Low power consumption
• Remote or local control
• Simple installation
• Interoperability
Application of Z-Wave protocol
• Smart product and IoT based application
• Energy saving
• Home security

ZigBee Smart Energy

ZigBee may be a low power, low rate wireless personal area network communication protocol. it’s mostly utilized in home automation and industrial settings. Since ZigBee may be a low power communication protocol, the IoT power devices used with ZigBee technology. The ZigBee communication protocol is predicated on the IEEE 802.15.4 standard operating at the two .4GHz frequency. The ZigBee protocol supports star, cluster or wireless mesh technology topology.
ZigBee uses the subsequent devices in its network:
• Zigbee Coordinator
• Zigbee End Device
• Zigbee Router

Properties of ZigBee protocol
• Standard: ZigBee 3.0 supported IEEE802.15.4
• Frequency: 2.4GHz
• Range: 10-100m
• Data transfer rate: 250kbps
Advantages of ZigBee protocol
• Wireless
• Mesh networking
• Direct communication
• Low power consumption
Disadvantages of ZigBee protocol
• Costly
• Works with low speed within alittle distance
Application of ZigBee protocol
• Commercial and residential control
• Personal and healthcare
• Home networking
• Industrial control and management
• Consumer electronics

LoRaWAN

LoRaWAN refers to Long Rage Wide Area Network which may be a wide area network protocol. it’s an optimized low-power consumption protocol design to support large-scale public networks with many low-power devices. one operator operates the LoRaWAN. The LoRaWAN network may be a bi-directional communication for IoT application with low cost, mobility, and security.
Properties of LoRaWAN protocol
• Standard: LoRaWAN
• Frequency: Various
• Range: 2-5km (urban environment), 15km (suburban environment)
• Data Rates: 0.3-50 kbps.
